CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 487,772, dated December13, 1892.

Application filed February 25. 1892. Serial No. 422,762. (No model.)

To all whom it may concern:

Be it known that I, EDWIN B. REID, of the town of Barrie, in the countyof Simooe, in the Province of Ontario, Canada, have invented a certainnew and Improved Automatic Car- Ooupler, of which the following is aspecification.

The object of the invention is to produce a simply-constructedself-acting car-coupler; and it consists in the peculiar construction,arrangement, and combinations of parts hereinafter more particularlydescribed, andthen definitely claimed.

In the accompanying drawings, Figure l is a perspective view of myimproved automatic car-coupler, showing the heads connected together.Fig. 2 is a perspective view of one of the heads, showing the positionof the lockingroller set to connect. Fig. 3 shows one end of a car witha head of my car-coupler in position. Fig. 4 is a view of my couplerwith the locking-rollers removed and a coupling-pin substituted. Fig. 5is a view of the draw-head with the link in a hori-' zontal position.

A is the head of the coupler, which is connected to the car in theordinary way. Each car is furnished with a head A, constructed in everyrespect like each other and formed, as shown in Fig. 4, so as to fittogether and leave a round hole between them, into which the insertionof a pin will lock the two heads together. Each head A is provided withone half of What I term a locking-roller B. Each half of thelocking-roller B is .suitably held in position and arranged so that aspring shall hold the face a of the roller B at an angle, as indicatedin Fig. 2.

I do not wish to confine myself to the manner in which each half of thelocking-roller B is held in position or how the spring is arranged toaccomplish the purpose specified; but in this specification I show apractical form to effect the desired end and which consists of aflangef, formed on the top end of the roller B to rest upon the top ofthe head A, and a similar flange d on the bottom end of the roller B andarranged to butt against the bottom side of the head A. This flangeextends over the edge of the head A, and each flange has a hole in it,through which a vertical key 0 is inserted. To this key O,Iconnect ahorizontal rod D, carried in suitable bearings and provided with aspiral spring E, set so that its tension shall hold the roller B in theposition shown in Fig. 2.

A crank-rod F is connected to the rod D and arranged as indicated, sothat the roller B may be caused to revolve, for the purpose hereinafterspecified.

When the two heads A are brought together, the nose b on each head comesin contact with the face a of the roller B, carried in the oppositehead, and in this way each roller Bis revolved on its pivot, so as topermit the nose I) to pass it. The instant the nose 19 passes the rollerB the said roller is revolved on its pivot by the action of the springE, thereby bringing both halves of the said roller back intotheir-initial position, (shown in Fig. 2,) thus locking the headstogether.

In order to unlock the heads, it is merely necessary to rock thecrank-rod F, so as to bring the faces a on a line with the center of thedraw-head, thereby unlocking the coupler and permitting the two heads tobe drawn apart.

In order to permit my coupler to connect with an ordinary link-coupling,I connect to each head A a link G, which when not required hangs down inthe position indicated in Figs. 1, 2, and 4. \Vhen required for use, Iraise it in a horizontal position, as shown in Fig. 5, making a notch gin the roller B, so as to support the said link in the desired position.

By removing the halt-roller from each head A the two heads A may becoupled together by the insertion of a pin H, as shown in Fig. a.

What I claim as my invention is 1. An improved automaticcar-couplerconsisting of a draw-head shaped substantially as shown andprovided with one half of a locking-roller B, a flange f on each end ofsaid halfiroller, a key 0, connecting said flanges, and a rod D,connected to the key 0, and controlled by the spring E, the whole beingar ranged to engage with a similarly-formed draw-head, substantially asdescribed.

2. Aniinprovedautoinatic car-coupler consisting of a draw-head shapedsubstantially and a link G, connected to the draw-head and as shown andprovided with one half of a arranged to hang vertically when not in uselocking-roller B, movably held in position by and to be supported in asubstantially-horithe key 0, actuated by a spiral spring on the zontalposition by said notch 9 when conp- I5 5 rod D and arranged to engagewith the other ling with another draw-head, substantially as half of alocking-roller carried ina similarlydescribed.

formed draw-head, substantially as and for Barrie, February 5, 1802.
